Setting Up the Cisco RV180/RV180W Using the Setup Wizard
1
Setting Up the Cisco RV180/RV180W Using the Setup Wizard
With the RV180/RV180W powered on and connected to a PC, use the Setup
Wizard to configure the Cisco RV180/RV180W.
To use the Setup Wizard:
STEP 1 Start the PC connected to the RV180/RV180W. Your computer becomes a DHCP
client of the RV180/RV180W and receives an IP address in the 192.168.1.xxx
range.
STEP 2 Launch a web browser and enter 192.168.1.1 in the Address field. This is the
default IP address of the RV180/RV180W.
A message appears about the site’s security certificate. The RV110W uses a selfsigned security certificate and this message appears because the router is not
known to your computer.
STEP 3 Click Continue to this website (or the option shown on your particular web
browser) to go to the web site.
The router’s default IP address is 192.168.1.1. If there is another device connected
to the network that is acting as a DHCP server, that device may assign a different
address to the RV180/RV180W. If so, use that IP address to connect to the RV180/
RV180W.
STEP 4 When the login page appears, enter the user name and password. The default
user name is cisco. The default password is cisco. Passwords are case sensitive.
To protect your router, change the default user name and password as soon as
possible. See the “Configuring User Accounts” section on page 135.
STEP 5 Click Log In. The Setup Wizard starts.
STEP 6 Follow the Setup Wizard’s on-screen instructions to set up the RV180/RV180W.
The Setup Wizard tries to automatically detect and configure your connection. If it
cannot, the Setup Wizard may ask you for information about your Internet
connection. You may need to contact your ISP to obtain this information.
After the Setup Wizard is done configuring the RV180/RV180W, the Getting
Started page appears. See Using the Getting Started Page, page 17 for more
information.

The RV180W provides the following modes:
Router
The Cisco RV180W acts as the wireless router in the network.
Access Point
The Cisco RV180W acts as the access point in the network. The WAN port is
disabled, and the four Ethernet ports can be used to connect to another router or
switch. The RV180W has the default IP address of 192.168.1.245. If you are
connecting the RV180W to a network that uses 802.1x for authentication, you must
enable 802.1x on the RV180W. See Configuring 802.1x Port-Based
Authentication, page 126.
WDS Bridge
The Cisco RV180W acts as a wireless bridge to another wireless network. To set
up the RV180W as a WDS bridge, perform the following tasks:
STEP 1 Connect the PC on which you will be using the Device Manager to the primary
wireless host (in this example, called “Router A”).
STEP 2 Connect one of the LAN ports on Router A with one of the LAN ports on the Cisco
RV180W.
STEP 3 On your PC, set your IP address to a static IP address that is on the same subnet
as the Cisco RV180W. For example, change your PC’s IP address to 192.168.1.30.
STEP 4 Enable WDS on Router A and the RV180W. (On the RV180W, choose Wireless >
WDS. Check Enable, and click Save.)

STEP 5 On the RV180W, enter the Router A’s MAC address of the wireless network
(access point). For example, if Router A is a Cisco RV220W, you would find the
MAC address of its wireless network under Status > System Summary, in the
Available Access Points table. To enter Router A’s MAC address into the RV180W:
a. Choose Wireless > WDS.
b. In the WDS Peer Table, click Add and enter the MAC address of the host router
(Router A)’s wireless network.
c. Click Save. For more information, see the “Configuring a Wireless Distribution
System (WDS)” section on page 73.
STEP 6 On Router A, enter the MAC address of the wireless network on the RV180W. Enter
only the MAC address of SSID 1 on router A because only SSID 1 supports WDS.
(To view the available RV180W access points and their MAC addresses, go to
Status > System Summary and look at the Available Access Point Table.)
STEP 7 Disconnect the Ethernet connection between Router A and the RV180W. After the
WDS connection is established, you should be able to ping the RV180W from the
PC that is connected to Router A.
The following situations may apply, depending on the host router and RV180W
configuration:
•
You may need to reboot the RV180W after configuring WDS and
disconnecting it from the host router.
•
If both routers are powered off, you may need to wait a few seconds after
turning on the host router to turn on the RV180w.
WDS Repeater
The Cisco RV180W connects using wireless to another wireless network and
repeats the wireless signal to clients behind the Cisco RV180W. You must
configure the MAC address of the AP or peers in order to allow them to associate
to the RV180W. See the “Configuring a Wireless Distribution System (WDS)”
section on page 73.

Connecting Devices to Your Wireless Network
To connect a device such as a PC or printer to your wireless network, you must
configure the wireless connection on the device using the security information you
configured for the Cisco RV180/RV180W:
•
Network name or Service Set Identifier (SSID). The default SSID is
ciscosb-1.
•
If applicable, the encryption type and security key.
Configuration Next Steps
Although the Setup Wizard automatically configures the RV180/RV180W, we
recommend that you change some default settings to provide better security and
performance.
In addition, you may need to manually configure some settings. A suggested
outline of steps follows:
•
Change the administrator name and password—See “Configuring User
Accounts” on page 135.
•
Change the idle timeout value—By default, The Device Manager logs you
out after 10 minutes of inactivity. This can be frustrating if you are trying to
configure your device. See “Setting the Session Timeout Value” on page
136.
•
(Optional) If you already have a DHCP server on your network, and you do
not want the Cisco RV180/RV180W to act as a DHCP server, see
“Configuring the LAN (Local Network) Settings” section on page 32.

Configuring Static DHCP
The DHCP server function allows you to add the MAC address and IP address of
endpoints that will connect to the network. When the endpoint connects to the
router, the DHCP server identifies any endpoints that have been configured. If an
endpoint has been configured in the server, the server assigns it the customized IP
address. If the endpoint is not configured in the server, it is assigned an IP address
from the generic DHCP pool.
STEP 1 Choose Networking > LAN (Local Network) > Static DHCP.
STEP 2 Click Add.
STEP 3 Enter the IP address of the device.
STEP 4 Enter the MAC address of the device. The format for the MAC Address is
XX:XX:XX:XX:XX:XX where X is a number from 0 to 9 (inclusive) or an alphabetical
letter between A and F (inclusive).
NOTE: The IP Address assigned should be outside the pool of the DHCP
addresses configured on the router. The DHCP pool is treated as generic pool and
all reserved IPs should be outside this pool. The DHCP server will then serve the
reserved IP address when the device using the corresponding MAC address

STEP 2 The list of endpoints is displayed; you cannot edit this list.
Configuring RSTP (Cisco RV180W)
Rapid Spanning Tree Protocol (RSTP) is a network protocol that prevents loops in
the network and dynamically reconfigures which physical links should forward
frames. When RTSP is configured, multiple paths to the root networking node are
created. Backup paths are automatically disabled unless the active path to the root
node is down. If that occurs, a backup path is enabled.
NOTE RSTP is not aware of virtual LANs (VLANs) in a network, so it is not recommended
for use in a network with VLANs.
To configure RTSP:
STEP 1 Choose Networking > LAN > RSTP.
STEP 2 Check Enable to enable RSTP.
STEP 3 Configure the following settings:
Bridge Priority
Enter a bridge priority from 0 to 61440 in
increments of 4096. Valid values are 0, 4096, 8192,
12288, 16384, 20480, 24576, 28672, 32768,
40960, 45056, 49152, 53248, 57344, and 61440.
This value is the priority component of the bridge
identifier of the network node. The lower the
system priority, the more likely the Cisco RV180W
is to become the root in the Spanning Tree. The
default is 327688.

Configuring Routing
Choosing the Routing Mode
The Cisco RV180/RV180W provides two different routing modes. Network
Address Translation (NAT), or gateway routing, is a technique that allows several
endpoints on a LAN to share an Internet connection. The computers on the LAN
use a “private” IP address range while the WAN port on the router is configured
with a single “public” IP address. The Cisco RV180/RV180W translates the internal
private addresses into a public address, hiding internal IP addresses from
computers on the Internet. If your ISP has assigned you a single IP address, you
want to use NAT so that the computers that connect through the Cisco RV180/
RV180W are assigned IP addresses from a private subnet (for example,
192.168.10.0).
The other routing mode, “router,” is used if your ISP has assigned you multiple IP
addresses so that you have an IP address for each endpoint on your network. You
must configure either static or dynamic routes if you use this type of routing. See
Configuring Static Routes, page 45, or Configuring Dynamic Routing, page 46.
To choose your routing mode:
STEP 1 Select Networking > Routing > Routing Mode.
STEP 2 Click the box next to the type of routing to configure.

Configuring Static Routes
You can configure static routes to direct packets to the destination network. A
static route is a pre-determined pathway that a packet must travel to reach a
specific host or network. Some ISPs require static routes to build your routing
table instead of using dynamic routing protocols. Static routes do not require CPU
resources to exchange routing information with a peer router. You can also use
static routes to reach peer routers that do not support dynamic routing protocols.
Static routes can be used together with dynamic routes. Be careful not to
introduce routing loops in your network.
Adding a Static Route
To create a static route:
STEP 1 Select Networking > Routing > Static Routes.
STEP 2 In the Static Route Table, click Add.
STEP 3 In the Route Name field, enter the name of the route.
STEP 4 If a route is to be immediately active, check the Active check box. When a route is
added in an inactive state, it will be listed in the routing table, but will not be used
by the router. The route can be enabled later. This feature is useful if the network
that the route connects to is not available when you added the route. When the
network becomes available, the route can be enabled.
STEP 5 Check the Private check box to mark this route as private, which means that it will
not be shared in a Routing Information Protocol (RIP) broadcast or multicast.
Uncheck this box if the route can be shared with other routers when RIP is
enabled.
STEP 6 In the Destination IP Address field, enter the IP address of the destination host or
network to which the route leads. For a standard Class C IP domain, the network
address is the first three fields of the Destination LAN IP; the last field should be
zero.
STEP 7 In the IP Subnet Mask field, enter the IPv4 Subnet Mask for the destination host or
network. For Class C IP domains, the Subnet Mask is 255.255.255.0.
STEP 8 From the Interface drop-down menu, choose the physical network interface
through which this route is accessible (WAN or LAN).
STEP 9 In the Gateway IP Address field, enter the IP Address of the gateway through
which the destination host or network can be reached. If this router is used to
connect your network to the Internet, then your gateway IP is the router's IP

address. If you have another router handling your network's Internet connection,
enter the IP address of that router instead.
STEP 10 In the Metric field, enter a value between 2 and 15 to define the priority of the
route. If multiple routes to the same destination exist, the route with the lowest
metric is chosen.
STEP 11 Click Save.
Configuring Dynamic Routing
RIP (Routing Information Protocol, RFC 2453) is an Interior Gateway Protocol (IGP)
that is commonly used in internal networks. It allows the Cisco RV180/RV180W to
exchange its routing information automatically with other routers, and allows it to
dynamically adjust its routing tables and adapt to changes in the network.
NOTE RIP is disabled by default on the Cisco RV180/RV180W.
To configure dynamic routing:
STEP 1 Choose Networking > Routing > Dynamic Routing.
STEP 2 To configure how the router sends and receives RIP packets, choose the RIP
direction:
•
None—The router neither broadcasts its route table nor does it accept any
RIP packets from other routers. This option disables RIP.
•
In Only—The router accepts RIP information from other router, but does not
broadcast its routing table.
•
Out Only—The router broadcasts its routing table periodically but does not
accept RIP information from other routers.
•
Both—The router both broadcasts its routing table and also processes RIP
information received from other routers.
STEP 3 Choose the RIP version:
•
Disabled.
•
RIP-1—This is a class-based routing version that does not include subnet
information. RIP-1 is the most commonly supported version.

Configuring Port Management
•
RIP-2B—This version broadcasts data in the entire subnet.
•
RIP-2M—This version sends data to multicast addresses.
STEP 4 RIP v2 authentication forces authentication of RIP packets before routes are
exchanged with other routers. It acts as a security feature because routes are
exchanged only with trusted routers in the network. RIP authentication is disabled
by default. You can enter two key parameters so that routes can be exchanged
with multiple routers present in the network. The second key also acts as a failsafe
when authorization with first key fails. To enable authentication for RIP-2B or RIP2M, check the Enable box. (You must also choose the direction as explained in
Step 2.)
STEP 5 If you enabled RIP v2 authentication, enter the following first and second key
parameters:
•
MD5 Key ID—Input the unique MD-5 key ID used to create the Authentication
Data for this RIP v2 message.
•
MD5 Auth Key—Input the auth key for this MD5 key, the auth key that is
encrypted and sent along with the RIP-V2 message.
•
Not Valid Before—Enter the start date when the auth key is valid for
authentication.
•
Not Valid After—Enter the end date when the auth key is valid for
authentication.

Configuring Router Advertisement
The Router Advertisement Daemon (RADVD) on the Cisco RV180/RV180W listens
for router solicitations in the IPv6 LAN and responds with router advertisements as
required. This is stateless IPv6 auto configuration, and the Cisco RV180/RV180W
distributes IPv6 prefixes to all nodes on the network.
To configure the RADVD:
STEP 1 Choose Networking > IPv6 > Router Advertisement.
STEP 2 Under Router Advertisement Status, choose Enable.

Configuring Networking
Configuring IPv6
STEP 3 Under Advertise Mode, choose one of the following:
•
Unsolicited Multicast—Select this option to send router advertisements
(RAs) to all interfaces belonging to the multicast group.
•
Unicast only—Select this option to restrict advertisements to well-known
IPv6 addresses only (router advertisements [RAs] are sent to the interface
belonging to the known address only).
STEP 4 If you chose Unsolicited Multicast in Step 3, enter the advertise interval. The
advertise interval is a random value between the Minimum Router Advertisement
Interval and Maximum Router Advertisement Interval. (MinRtrAdvInterval = 0.33 *
MaxRtrAdvInterval.) The default is 30 seconds.
STEP 5 Under RA Flags, check Managed to use the administered/stateful protocol for
address auto configuration. Check Other to use the administered/stateful protocol
of other, non-address information auto configuration.
STEP 6 Under router preference, choose Low, Medium, or High. The router preference
provides a preference metric for default routers. The low, medium and high values
are signaled in unused bits in Router Advertisement messages. This extension is
backward compatible, both for routers (setting the router preference value) and
hosts (interpreting the router preference value). These values are ignored by hosts
that do not implement router preference. This feature is useful if there are other
RADVD-enabled devices on the LAN. The default is high.
STEP 7 Enter the MTU size. The MTU is the size of the largest packet that can be sent over
the network. The MTU is used in RAs to ensure all nodes on the network use the
same MTU value when the LAN MTU is not well-known. The default is 1500 bytes.
STEP 8 Enter the router lifetime value, or the time in seconds that the advertisement
messages will exist on the route. The default is 3600 seconds.
STEP 9 Click Save.
Configuring Router Advertisement Prefixes
To configure the RADVD available prefixes:
STEP 1 Choose Networking > IPv6 > Advertisement Prefixes.
STEP 2 Click Add.

STEP 3 Choose the IPv6 Prefix Type:
•
6to4—6to4 is a system that allows IPv6 packets to be transmitted over an
IPv4 network. It is used when an end user wants to connect to the IPv6
Internet using their existing IPv4 connection
•
Global/Local/ISATAP—By using ISATAP, you can integrate IPv6 traffic into a
IPv4 network environment. ISATAP uses a locally assigned IPv4 address to
create a 64-bit interface identifier for IPv6.
STEP 4 If you chose 6to4 in Step 3, enter the Site-level aggregation identifier (SLA ID.) The
SLA ID in the 6to4 address prefix is set to the interface ID of the interface on which
the advertisements are sent.
STEP 5 If you chose Global/Local/ISATAP in Step 3, enter the IPv6 prefix and prefix length.
The IPv6 prefix specifies the IPv6 network address. The prefix length variable is a
decimal value that indicates the number of contiguous, higher-order bits of the
address that make up the network portion of the address.
STEP 6 Enter the prefix lifetime, or the length of time during which the requesting router is
allowed to use the prefix.

A Note About Wireless Security
Wireless networks are convenient and easy to install, so small businesses with
high-speed Internet access are adopting them at a rapid pace. Because wireless
networking operates by sending information over radio waves, it can be more
vulnerable to intruders than a traditional wired network. Like signals from your
cellular or cordless phones, signals from your wireless network can also be
intercepted. The following information will help you to improve your security:
•
Wireless Security Tips, page 61

Configuring the Wireless Network (Cisco RV180W)
A Note About Wireless Security

Wireless Security Tips
Since you cannot physically prevent someone from connecting to your wireless
network, you need to take some additional steps to keep your network secure:
•
Change the default wireless network name or SSID
Wireless devices have a default wireless network name or Service Set
Identifier (SSID) set by the factory. This is the name of your wireless
network, and can be up to 32 characters in length.
You should change the wireless network name to something unique to
distinguish your wireless network from other wireless networks that
may exist around you, but do not use personal information (such as your
Social Security number) because this information may be available for
anyone to see when browsing for wireless networks.
•
Change the default password
For wireless products such as access points, routers, and gateways, you
will be asked for a password when you want to change their settings.
These devices have a default password set by the factory. The default
password is often admin. Hackers know these defaults and may try to
use them to access your wireless device and change your network
settings. To thwart any unauthorized changes, customize the device’s
password so it will be hard to guess.
•
Enable MAC address filtering
Cisco routers and gateways give you the ability to enable Media Access
Control (MAC) address filtering. The MAC address is a unique series of
numbers and letters assigned to every networking device. With MAC
address filtering enabled, wireless network access is provided solely
for wireless devices with specific MAC addresses. For example, you can
specify the MAC address of each computer in your network so that only
those computers can access your wireless network.
Cisco RV180/RV180W Administration Guide

Enable encryption
Encryption protects data transmitted over a wireless network. Wi-Fi
Protected Access (WPA/WPA2) and Wired Equivalency Privacy (WEP)
offer different levels of security for wireless communication. Currently,
devices that are Wi-Fi certified are required to support WPA2, but are
not required to support WEP.
A network encrypted with WPA/WPA2 is more secure than a network
encrypted with WEP, because WPA/WPA2 uses dynamic key
encryption. To protect the information as it passes over the airwaves,
you should enable the highest level of encryption supported by your
network equipment.
WEP is an older encryption standard and may be the only option
available on some older devices that do not support WPA.
•
Keep wireless routers, access points, or gateways away from exterior walls
and windows.
•
Turn wireless routers, access points, or gateways off when they are not
being used (at night, during vacations).
•
Use strong passphrases that are at least eight characters in length.
Combine letters and numbers to avoid using standard words that can be
found in the dictionary.
General Network Security Guidelines
Wireless network security is useless if the underlying network is not secure. Cisco
recommends that you take the following precautions:
•
Password protect all computers on the network and individually password
protect sensitive files.
•
Change passwords on a regular basis.
•
Install anti-virus software and personal router software.
•
Disable file sharing (peer-to-peer). Some applications may open file sharing
without your consent and/or knowledge.

Understanding the Cisco RV180W’s Wireless Networks
The Cisco Small Business RV180W Wireless-N Multifunction Router provides four
separate virtual wireless networks. These networks can be configured and
enabled with individual settings. You can set up the multiple networks to segment
the network traffic, to allow different levels of access, such as guest access, or to
allow access for different functions such as accounting, billing, and so on.
Configuring Basic Wireless Settings
The following sections contain information on how to configure basic wireless
settings on the Cisco RV180W. These settings apply to all of the wireless
networks.
Configuring Radio, Mode, and Channel Settings
STEP 1 Choose Wireless > Basic Settings.
STEP 2 In the Radio field, choose Enable to enable wireless functionality for the
Cisco RV180W. Choosing Disable turns off wireless functionality for the router.
STEP 3 In the Wireless Network Mode field, choose the type of wireless network based
on the devices you have that will connect to the network:
•
B/G Mixed—Select this mode if you have devices in the network that
support 802.11b and 802.11g.
•
G Only—Select this mode if all devices in the wireless network only support
802.11g.
•
B/G/N Mixed—Select this mode if you have devices in the network that
support 802.11b, 802.11g and 802.11n.
•
N Only—Select this mode only if all devices in the wireless network support
802.11n.
•
G/N Mixed—Select this mode if you have devices in the network that
support 802.11g and 802.11n.
STEP 4 Select the channel bandwidth. Available choices depend on the wireless network
mode chosen in Step 3.
STEP 5 The Control Side Band field defines the sideband which is used for the secondary
or extension channel when the AP is operating in 40 Mhz channel width. Choose
Cisco RV180/RV180W Administration Guide
63
Configuring the Wireless Network (Cisco RV180W)
Configuring Basic Wireless Settings
3
lower or upper. The signal components above the carrier frequency constitute the
upper sideband (USB) and those below the carrier frequency constitute the lower
sideband (LSB).
STEP 6 The Wireless Channel field specifies the frequency that the radio uses to transmit
wireless frames. Select a channel from the list of channels or choose auto to let the
Cisco RV180W determine the best channel to use based on the environment noise
levels for the available channels.
STEP 7 In the U-APSD field, choose Enable to enable the Unscheduled Automatic Power
Save Delivery (also referred to as WMM Power Save) feature that allows the radio
to conserve power. This feature is disabled by default.
STEP 8 Click Save.
Configuring Wireless Security and Other Settings
At a minimum, you should edit the default profiles to enable wireless security. See
A Note About Wireless Security, page 60.
You can configure wireless security and other settings for each wireless network.
To configure wireless settings:
STEP 1 Choose Wireless > Basic Settings.
STEP 2 In the Wireless Basic Settings Table, check the box on the left of the wireless
network you want to configure.
STEP 3 Click Edit to configure these network properties:
a. Enter the SSID name, or the unique name for this wireless network. Include up
to 32 characters, using any of the characters on the keyboard. For added
security, you should change the default value to a unique name.
b. Check the Broadcast SSID box if you want to allow all wireless clients within
range to be able to detect this wireless network when they are scanning the
local area for available networks. Disable this feature if you do not want to make
the SSID known. When this feature is disabled, wireless users can connect to
your wireless network only if they know the SSID (and provide the required
security credentials).
c. Enter the VLAN, or network for this wireless network. (See Chapter 2,
Configuring Networking, for more information on VLANs.) Devices connecting
to this network are assigned addresses on this VLAN. The default VLAN is 1
and if all the devices are on the same network, this can be left unchanged.

d. (Optional) Check the Wireless Isolation within SSID box to separate all wireless
clients within the SSID. When this feature is enabled, the wireless client can
communicate with the Cisco RV180W, but not with other clients connected
wirelessly to that SSID. For example, if the Cisco RV180W has many wireless
users, you can prevent users from accessing other parts of the network.
e. In the Max Associated Clients field, enter the maximum number of endpoints
that can connect to this network. The default value is 8. You can change this
number if you want to restrict traffic on the network to prevent it from being
overloaded, for example. The number of clients connected across all four
virtual access points cannot exceed 100.

Click Save.
Configuring Security
STEP 1 Choose Wireless > Basic Settings.
STEP 2 In the Wireless Basic Settings Table, check the box on the left of the wireless
network you want to configure.
STEP 3 Click Edit Security Mode to configure security.
STEP 4 Select the SSID to configure.
STEP 5 Click Enable under Wireless Isolation within SSID to separate all wireless clients
within the SSID.
STEP 6 In the Security field, select the type of security. All devices on this network must
use the same security mode and settings to work correctly. Cisco recommends
using the highest level of security that is supported by the devices in your
network.
•
Disabled—Any device can connect to the network. Not recommended.
•
Wired Equivalent Privacy (WEP)— Weak security with a basic encryption
method that is not as secure as WPA. WEP may be required if your network
devices do not support WPA; however, it is not recommended.
•
Wi-Fi Protected Access (WPA) Personal—WPA is part of the wireless
security standard (802.11i) standardized by the Wi-Fi Alliance and was
intended as an intermediate measure to take the place of WEP while the
Cisco RV180/RV180W Administration Guide
65
Configuring the Wireless Network (Cisco RV180W)
Configuring Basic Wireless Settings
3
802.11i standard was being prepared. It supports TKIP/AES encryption. The
personal authentication is the preshared key (PSK) that is an alphanumeric
passphrase shared with the wireless peer.
•
WPA Enterprise—Allows you to use WPA with RADIUS server
authentication.
•
WPA2 Personal—WPA2 is the implementation of security standard
specified in the final 802.11i standard. It supports AES encryption and this
option uses preshared key (PSK) based authentication.
•
WPA2 Personal Mixed—Allows both WPA and WPA2 clients to connect
simultaneously using PSK authentication.
•
WPA2 Enterprise—Allows you to use WPA2 with RADIUS server
authentication.
•
WPA2 Enterprise Mixed—Allows both WPA and WPA2 clients to connect
simultaneously using RADIUS authentication.
STEP 7 The Encryption Type appears based on the type of network you chose in Step 3:
•
WPA Personal, WPA Enterprise, WPA2 Personal Mixed, WPA2 Enterprise
Mixed—TKIP+AES
•
WPA2 Personal, WPA2 Enterprise—AES
STEP 8 If you chose WEP:
a. In the Authentication field, choose Open System or Shared Key. If you choose
Open System, a wireless client doesn't need to provide a shared key in order to
access the wireless network. Any client can associate to the router. If you
choose Shared Key, a wireless client must provide the correct shared key
(password) in order to access the wireless network.
b. Select the Encryption Type (64- or 128-bit WEP). The larger size keys provide
stronger encryption, making the key more difficult to crack (for example, 64-bit
WEP has a 40-bit key which is less secure than the 128-bit WEP, which has a
104-bit key).
c. (Optional) In the WEP Passphrase field, enter an alphanumeric phrase (longer
than eight characters for optimal security) and click Generate Key to generate
four unique WEP keys in the WEP Key fields below.
d. Select one of the four keys to use as the shared key that devices must have in
order to use the wireless network. If you did not generate a key in Step 7c,
enter a key directly into the WEP Key field. The length of the key should be 5
ASCII characters (or 10 hexadecimal characters) for 64-bit WEP and 13 ASCII
Cisco RV180/RV180W Administration Guide
66
Configuring the Wireless Network (Cisco RV180W)
Configuring Basic Wireless Settings
3
characters (or 26 hexadecimal characters) for 128-bit WEP. Valid hexadecimal
characters are “0” to “9” and “A” to “F”.
STEP 9 If you chose WPA Personal, WPA2 Personal, or WPA2 Personal Mixed:
a. Enter the WPA Key, or password/phrase that will secure the network. Devices
connecting to the network must use this phrase for authentication.
b. If you want to see the password as you are entering it, check the Unmask
Password box.
c. In the Key Renewal field, enter the number of seconds after which the Cisco
RV180W will generate a new key. These keys are internal keys exchanged
between the Cisco RV180W and connected devices. The default value (3600
seconds) is usually adequate unless you are experiencing network problems.
STEP 10 If you chose WPA Enterprise or WPA2 Enterprise Mixed, no further configuration is
required.
STEP 11 If you chose WPA2 Enterprise, you can check the Pre-Authentication box
(optional). Pre-authentication allows wireless clients to quickly switch between
connected wireless networks sharing the same security configuration. When a
wireless client disconnects from a wireless network, a notification is sent to the
network, which then sends the pre-authentication info to other wireless networks.
STEP 12 Click Save.
Configuring MAC Filtering
You can use MAC filtering to permit or deny access to the wireless network based
on the MAC (hardware) address of the requesting device. For example, you can
enter the MAC addresses of a set of PCs and only allow those PCs to access the
network. MAC filtering is configured for each wireless network.
STEP 1 Choose Wireless > Basic Settings.
STEP 2 In the Wireless Basic Settings Table, check the box on the left of the wireless
network you want to configure.
STEP 3 Click Edit MAC Filtering.
STEP 4 Choose Enable.
STEP 5 Under Connection Control, choose one of the following:

•
Block following MAC addresses from connecting to wireless network—
Blocks MAC addresses specified below from connecting to the wireless
network.
•
Allow only following MAC addresses to connect to wireless network—
Allows only the MAC addresses specified below to connect to the wireless
network.
STEP 6 Enter the MAC addresses of the endpoints to allow or deny. To see a list of
currently-connected clients, click Wireless Clients List.
STEP 7 Click Save.
Configuring Wi-Fi Multimedia
Wi-Fi Multimedia (WMM) is used to prioritize different types of traffic. You can
configure QoS settings to provide different priority to different applications, users,
or data flows, or to guarantee a certain level of performance to a data flow.
To configure WMM:
STEP 1 Choose Wireless > Basic Settings.
STEP 2 In the Wireless Basic Settings Table, check the box on the left of the wireless
network you want to configure.
STEP 3 Click Edit WMM.
STEP 4 In the SSID field, select SSID that clients use to connect to the AP.
STEP 5 Check the WMM Enable box to enable WMM based on the IEEE 802.11e standard
for this profile. WMM helps in prioritizing wireless traffic according to four access
categories:
•
Voice (highest priority, 4)
•
Video (high priority, 3)
•
Best effort (medium priority, 2)
•
Background (lowest priority, 1)
STEP 6 In the DSCP to Queue table, for each ingress DSCP, you can choose the output
queue for the traffic. The Differentiated Services Code Point (DSCP) field identifies
the data packet and the output queue identifies the output queue in which the
packet is transmitted:
Cisco RV180/RV180W Administration Guide
68
Configuring the Wireless Network (Cisco RV180W)
Configuring Basic Wireless Settings
3
•
Voice (4) or Video (3)—High priority queue, minimum delay. Typically used to
send time-sensitive data such as video and other streaming media.
•
Best Effort (2)—Medium priority queue, medium throughput and delay. Most
traditional IP data is sent to this queue.
•
Background (1)—Lowest priority queue, high throughput. Bulk data that
requires maximum throughput and is not time-sensitive is typically sent to
this queue (FTP data, for example).
If you want to change the output queue for packets marked with a particular DSCP,
select the new output queue from the drop-down list.
STEP 7 Click Save.
Configuring Wireless Network (SSID) Scheduling
You can configure each of the four available wireless networks on the Cisco
RV180W to be active during certain times of the day. To configure the schedule for
a wireless network:
STEP 1 Choose Wireless > Basic Settings.
STEP 2 In the Wireless Basic Settings Table, check the box on the left of the wireless
network you want to configure.
STEP 3 Select the wireless network for which you want to create a schedule.
STEP 4 Click Edit SSID Scheduling.
STEP 5 Check the Enable box to allow you to create a schedule to make the network
active during certain times.
STEP 6 Enter the start and stop times for the network to be active.
STEP 7 Click Save.

69
Configuring the Wireless Network (Cisco RV180W)
Configuring Advanced Wireless Settings
3
Configuring Advanced Wireless Settings
To configure advanced wireless settings on the Cisco RV180W:
STEP 1 Choose Wireless > Advanced Settings.
STEP 2 In the Beacon Interval field, enter the time in milliseconds between beacon
transmissions. The default interval is 100 milliseconds.
STEP 3 In the DTIM Interval field, enter the interval at which the delivery traffic indication
message should be sent. A DTIM field is a countdown field informing clients of the
next window for listening to broadcast and multicast messages. When the Cisco
RV180W has buffered broadcast or multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and
awaken to receive the broadcast and multicast messages.The default interval is 2
beacon intervals.
STEP 4 The Request to Send (RTS) Threshold is the packet size, in bytes, that requires the
AP to check the transmitting frames to determine if an RTS/Clear to Send (CTS)
handshake is required with the receiving client. Using a small value causes RTS
packets to be sent more often, consuming more of the available bandwidth,
reducing the apparent throughput of the network packets. The default value is
2346, which effectively disables RTS.
STEP 5 The Fragmentation Threshold is the maximum length of the frame, in bytes,
beyond which packets must be fragmented into two or more frames. Collisions
occur more often for long frames because while sending them, they occupy the
channel for a longer time. The default value is 2346, which effectively disables
fragmentation. If you experience a high packet error rate, you can slightly increase
the fragmentation threshold; setting the fragmentation threshold too low may
result in poor network performance. Only minor reduction of the default value is
recommended.
STEP 6 Choose the Preamble Mode. The 802.11b standard requires that a preamble be
appended to every frame before it is transmitted through the air. The preamble
may be either the traditional “long” preamble, which requires 192 μs for
transmission, or it may be an optional “short” preamble that requires only 96 μs. A
long preamble is needed for compatibility with the legacy 802.11 systems
operating at 1 and 2 Mbps. The default selection is long.
STEP 7 Choose the Protection Mode. Select none (the default) to turn off CTS. The CTS-
to-Self Protection option enables the CTS-to-Self protection mechanism, which is
used to minimize collisions among stations in a mixed 802.11b and 802.11g
environment. This function boosts the Cisco RV180W’s ability to catch all wireless
transmissions but severely decreases performance.

A Wireless Distribution System (WDS) is a system that enables the wireless
interconnection of access points in a network. It allows a wireless network to be
expanded using multiple access points without the need for a wired backbone to
link them.
WDS peers are other access points in the network connected in the WDS. All
base stations in a WDS must be configured to use the same radio channel, method
of encryption (none, WEP, or WPA) and encryption keys.
You need to configure WDS if you are using the Cisco RV180W in WDS Bridge or
WDS Repeater mode. See Choosing the Device Mode (Cisco RV180W),
page 15.

Cisco RV180/RV180W Firewall Features
You can secure your network by creating and applying access rules that the
Cisco RV180/RV180W uses to selectively block and allow inbound and outbound
Internet traffic. You then specify how and to what devices the rules apply. You can
configure the following:
•
Services or traffic types (examples: web browsing, VoIP, other standard
services and also custom services that you define) that the router should
allow or block.
•
Rules for outbound (from your LAN to the Internet) or inbound (from the
Internet to your LAN) traffic.

•
Schedules as to when the router should apply rules.
•
Keywords (in a domain name or on a URL of a web page) that the router
should allow or block.
•
MAC addresses of devices whose inbound access to your network the
router should block.
•
Port triggers that signal the router to allow or block access to specified
services as defined by port number.
•
Reports and alerts that you want the router to send to you.
You can, for example, establish restricted-access policies based on time-of-day,
web addresses, and web address keywords. You can block Internet access by
applications and services on the LAN, such as chat rooms or games. You can block
just certain groups of PCs on your network from being accessed by the WAN or
public network.
Inbound (Internet to LAN) rules restrict access to traffic entering your network,
selectively allowing only specific outside users to access specific local resources.
By default, all access from the insecure WAN side is blocked from accessing the
secure LAN, except in response to requests from the LAN or DMZ. To allow
outside devices to access services on the secure LAN, you must create a firewall
rule for each service.
If you want to allow incoming traffic, you must make the router's WAN port IP
address known to the public. This is called “exposing your host.” How you make
your address known depends on how the WAN ports are configured; for the
Cisco RV180/RV180W, you may use the IP address if a static address is assigned
to the WAN port, or if your WAN address is dynamic, a DDNS (Dynamic DNS) name
can be used.
Outbound (LAN to Internet) rules restrict access to traffic leaving your network,
selectively allowing only specific local users to access specific outside resources.
The default outbound rule is to allow access from the secure zone (LAN) to the
insecure WAN. To block hosts on the secure LAN from accessing services on the
outside (insecure WAN), you must create a firewall rule for each service.

Configuring Access Rules
Configure access rules to control traffic to and from your network. To configure
access rules, choose Firewall > Access Rules. All configured firewall rules on the
Cisco RV180/RV180W are displayed in the Access Rule Table.
Configuring the Default Outbound Policy
You can configure the default outbound policy for the traffic that is directed from
your secure network (LAN) to the Internet. The default inbound policy for traffic
flowing from the Internet to your LAN is always blocked and cannot be changed.
The default outbound policy applies to traffic that is not covered by the specific
firewall rules that you have configured. For example, you may have specific
firewall rules restricting outbound instant messaging and video traffic, but all other
traffic would be permitted if you choose allow as the default outbound policy.
To configure the default outbound policy:
STEP 1 Choose Firewall > Access Rules.
STEP 2 Under Default Outbound Policy, choose Allow or Block. Allow permits traffic from
your LAN to the Internet. Block does not permit traffic from your LAN to the
Internet.
STEP 3 Click Save.
Using the Access Rules Table
In the Access Rules table, you can add, edit, enable, disable, and delete access
rules. Check the box next to the rule on which you want to perform the action, then
select the action from the buttons below the table.
Reordering Access Rules
You may want to reorder the access rules you have created to change the priority
of a rule. To reorder access rules:
STEP 1 Click Reorder.
STEP 2 In the Access Rule Table, check the rule that you want to move, and click the Up or
Down arrow to move it up or down the list.
STEP 3 Click Save.

STEP 6 In the Source IP field, configure the IP address to which the firewall rule applies:
•
Any—The rule applies to traffic originating from any IP address in the local
network.
•
Single Address—The rule applies to traffic originating from a single IP
address in the local network. Enter the address in the Start field.
•
Address Range—The rule applies to traffic originating from an IP address
located in a range of addresses. Enter the starting IP address in the Start
field, and the ending IP address in the Finish field.
STEP 7 If you are configuring an inbound firewall access rule:
a. Destination Network Address Translation (DNAT) maps a public IP address
(your dedicated WAN address) to an IP address on your private network. In the
Send to Local Server (DNAT IP) field, specify an IP address of a machine on the
Local Network which is hosting the server.
b. The router supports multi-NAT, so your Internet Destination IP address does not
have to be the address of your WAN. On a single WAN interface, multiple public
IP addresses are supported. If your ISP assigns you more than one public IP
address, one of these can be used as your primary IP address on the WAN
port, and the others can be assigned to servers on the LAN. In this way, the
LAN can be accessed from the internet by its aliased public IP address. Check
the Enable box and enter the IP address you want to use.
c. Under Rule Status, choose Enabled or Disabled. You may want to configure a
rule and choose Disabled if you want to enable it at a later time.

Configuring Attack Prevention
STEP 8 If you are configuring an outbound firewall access rule:
a. In the Destination IP field, configure the IP address to which the firewall rule
applies:
•
Any—The rule applies to traffic going to any IP address.
•
Single Address—The rule applies to traffic going to a single IP address.
Enter the address in the Start field.
•
Address Range—The rule applies to traffic going to an IP address located in
a range of addresses. Enter the starting IP address in the Start field, and the
ending IP address in the Finish field.
b. You can configure Secure Network Address Translation (SNAT) to map a public
IP address (your Dedicated WAN address, Optional WAN address, or another
address) to an IP address on your private network. Under Use This SNAT IP
Address, check Enable and enter the SNAT IP Address.
c. Under Rule Status, choose Enabled or Disabled. You may want to configure a
rule and choose Disabled if you want to enable it at a later time.
Configuring Attack Prevention
Attacks are malicious security breaches or unintentional network issues that
render the Cisco RV180/RV180W unusable. Attack prevention allows you to
manage WAN security threats such as continual ping requests and discovery via
ARP scans. TCP and UDP flood attack prevention can be enabled to manage
extreme usage of WAN resources.
As well, certain Denial-of-Service (DoS) attacks can be blocked. These attacks, if
uninhibited, can use up processing power and bandwidth and prevent regular
network services from running normally. ICMP packet flooding, SYN traffic
flooding, and Echo storm thresholds can be configured to temporarily suspend
traffic from the offending source.
To configure attack prevention:
STEP 1 Choose Firewall > Attack Prevention.

STEP 2 Check the boxes to enable the following functions:
•
•
WAN (Internet) Security Checks
-
Respond to Ping on WAN (Internet)—To configure the Cisco RV180/
RV180W to allow a response to an Internet Control Message Protocol
(ICMP) Echo (ping) request on the WAN interface, check this box. This
setting is used as a diagnostic tool for connectivity problems. Not
enabled by default.
-
Stealth Mode—If Stealth Mode is enabled, the router will not respond to
port scans from the WAN. This feature makes the network less
susceptible to discovery and attacks. Enabled by default.
-
Flood— If this option is enabled, the router will drop all invalid TCP
packets. This feature protects the network from a SYN flood attack.
Enabled by default.
LAN (Local Network) Security Checks
-
•
Block UDP Flood—If this option is enabled, the router will not accept
more than 500 simultaneous, active UDP connections from a single
computer on the LAN. Enabled by default.
ICSA (International Computer Security Association) Settings
-
Block Anonymous ICMP Messages—ICSA requires the firewall to silently
block without sending an ICMP notification to the sender. Some
protocols, such as MTU Path Discovery, require ICMP notifications.
Enable this setting to operate in “stealth” mode. Enabled by default.
-
Block Fragmented Packets—ICSA requires the firewall to block
fragmented packets from ANY to ANY. Enabled by default.
-
Block Multicast Packets—ICSA requires the firewall to block multicast
packets. Enabled by default.
STEP 3 Click Save.
Configuring Content Filtering
The Cisco RV180/RV180W supports several content filtering options. You can
block certain web applications or components (such as ActiveX or Java). You can
set up trusted domains from which to always allow content.

Configuring Content Filtering
Enabling Content Filtering
To enable content filtering:
STEP 1 Choose Firewall > Content Filtering.
STEP 2 Check the Enable box.
STEP 3 Click Save.
Blocking Web Components
Certain commonly-used web components can be blocked for increased security.
Some of these components can be used by malicious websites to infect
computers that access them.
STEP 1 Choose Firewall > Content Filtering.
STEP 2 With content filtering enabled, under Web Components, select the check box for
each component you wish to block:
•
Block Proxy—A proxy server (or simply, proxy) allows computers to route
connections to other computers through the proxy, thus circumventing
certain firewall rules. For example, if connections to a specific IP address are
blocked by a firewall rule, the requests can be routed through a proxy that is
not blocked by the rule, rendering the restriction ineffective. Enabling this
feature blocks proxy servers.
•
Block Java—Blocks java applets from being downloaded from pages that
contain them. Java applets are small programs embedded in web pages that
enable dynamic functionality of the page. A malicious applet can be used to
compromise or infect computers. Enabling this setting blocks Java applets
from being downloaded.
•
Block ActiveX—Similar to Java applets, ActiveX controls are installed on a
Windows computer while running Internet Explorer. A malicious ActiveX
control can be used to compromise or infect computers. Enabling this setting
blocks ActiveX applets from being downloaded.

Configuring URL Blocking
•
Block Cookies—Cookies are used to store session information by websites
that usually require login. However, several websites use cookies to store
tracking information and browsing habits. Enabling this option filters out
cookies from being created by a website.
NOTE: Many websites require that cookies be accepted in order for the site to be
accessed properly. Blocking cookies can cause many websites to not function
properly.
STEP 3 Click Save.
Adding Trusted Domains
You can add a list of trusted domains. These domains are bypassed during
keyword filtering. For example, if “yahoo” is added to the blocked keywords list
and www.yahoo.com is added to the trusted domain list, then www.yahoo.com
will be allowed, but mail.yahoo.com will not be allowed.
NOTE Before adding trusted domains, you must enable content filtering. See Enabling
Content Filtering, page 85.
To add trusted domains:
STEP 1 Choose Firewall > Content Filtering. The Trusted Domain Table displays a list of
currently configured trusted domains.
STEP 2 Click Add and enter the name of the trusted domain.
STEP 3 Click Save.
Configuring URL Blocking
You can block access to websites that contain specific keywords in the URL or
page contents. If these keywords are found in the site's name (for example, web
site URL or newsgroup name), the site is blocked. To configure URL blocking:
STEP 1 Choose Firewall > URL Blocking. The table displays currently blocked keywords.
STEP 2 Click Add Row.
STEP 3 Under Status, check the box to enable blocking for the new keyword.

STEP 4 Select the group to which to apply the keyword blocking. If you need to configure
a new group, click Configure LAN Groups. (See Configuring LAN (Local
Network) Groups, page 98.)
STEP 5 Enter the keyword to block.
STEP 6 Click Save.
Configuring Port Triggering
Port triggering allows devices on the LAN to request one or more ports to be
forwarded to them. Port triggering waits for an outbound request from the LAN on
one of the defined outgoing ports, and then opens an incoming port for that
specified type of traffic. Port triggering is a form of dynamic port forwarding while
an application is transmitting data over the opened outgoing or incoming ports.
Port triggering opens an incoming port for a specific type of traffic on a defined
outgoing port.
Port triggering is more flexible than static port forwarding (available when
configuring firewall rules) because a rule does not have to reference a specific
LAN IP or IP range. Ports are also not left open when not in use, thereby providing
a level of security that port forwarding does not offer.
NOTE
Port triggering is not appropriate for servers on the LAN, since there is a
dependency on the LAN device making an outgoing connection before incoming
ports are opened.
Some applications require that, when external devices connect to them, they
receive data on a specific port or range of ports in order to function properly. The
router must send all incoming data for that application only on the required port or
range of ports. The gateway has a list of common applications and games with
corresponding outbound and inbound ports to open. You can also specify a port
triggering rule by defining the type of traffic (TCP or UDP) and the range of
incoming and outgoing ports to open when enabled.

Adding a Port Triggering Rule
To add a port triggering rule:
STEP 1 Choose Firewall > Port Triggering.
STEP 2 Click Add.
STEP 3 Specify an easily-identifiable name for this rule.
STEP 4 Check the Enable box to enable the rule.
STEP 5 Select whether the port uses TCP, UDP, or both protocols.
STEP 6 In the Outgoing (Trigger) Port Range section, specify the port number or range of
port numbers that will trigger this rule when a connection request from outgoing
traffic is made. If the outgoing connection uses only one port, then specify the
same port number in the Start Port and End Port fields.
STEP 7 In the Incoming (Response) Port Range section, specify the port number or range
of port numbers used by the remote system to respond to the request it receives.
If the incoming connection uses only one port, then specify the same port number
in the Start Port and End Port fields.
STEP 8 Click Save.
Configuring Port Forwarding
Port forwarding is used to redirect traffic from the Internet from one port on the
WAN to another port on the LAN. The port forwarding rules menu allows selection
of a service. Common services are available or you can define a custom service
and associated ports to forward.
The Port Forwarding Rule Table lists all the available port forwarding rules for this
device and allows you to configure port forwarding rules. The table contains the
following information:
•
Action—Whether to block or allow traffic (always or by schedule) that
meets these filter rules, and when the rule is applicable.
•
Service—Service for which this port forwarding rule is applicable.

Configuring a DMZ Host
The Cisco RV180/RV180W supports DMZ options. A DMZ is a sub-network that is
open to the public but behind the firewall. DMZ allows you to redirect packets
going to your WAN port IP address to a particular IP address in your LAN. It is
recommended that hosts that must be exposed to the WAN (such as web or e-mail
servers) be placed in the DMZ network. Firewall rules can be allowed to permit
access to specific services and ports to the DMZ from both the LAN or WAN. In
the event of an attack on any of the DMZ nodes, the LAN is not necessarily
vulnerable as well.
You must configure a fixed (static) IP address for the endpoint that will be
designated as the DMZ host. The DMZ host should be given an IP address in the
same subnet as the router's LAN IP address but it cannot be identical to the IP
address given to the LAN interface of this gateway.
STEP 1 Choose Firewall > DMZ Host.
STEP 2 Check the Enable box to enable DMZ on the network.
STEP 3 Enter the IP address for the endpoint that will receive the redirected packets. This
is the DMZ host.
STEP 4 Click Save. You must then configure firewall rules for the zone. See Creating
Custom Services, page 95.
Configuring Advanced Firewall Settings
This page allows you to configure many advanced firewall settings.
Configuring One-to-One Network Address Translation (NAT)
One-to-one NAT is a way to make systems behind a firewall that are configured
with private IP addresses appear to have public IP addresses.
To configure one-to-one NAT, choose Firewall > Advanced Settings > One-to-One
NAT. The One-to-One-NAT Rules Table lists the available One-To-One NAT rules
that have been configured. It displays the following fields:

address.
•
Range Length—Range length maps one to one private address to public
address up to the given range.
•
Service—Shows configured services. Services for one-to-one NAT allow
you to configure the service to be accepted by the private IP (LAN) address
when traffic is sent to the corresponding public IP address. Configured
services on private IP addresses in the range are accepted when traffic is
available on the corresponding public IP address.
Adding a One-to-One NAT Rule
To add a one-to-one NAT rule:
STEP 1 Choose Firewall > Advanced Settings > One-to-One NAT.
STEP 2 Click Add.
STEP 3 Enter information in the following fields:
•
Private Range Begin—The starting IP address in the private (LAN) IP
address.
•
Public Range Begin—The starting IP address in the public (WAN) IP address.
•
Range Length—Range length maps one to one private address to public
address up to the given range.
•
Service—Choose the service for which the rule applies.
STEP 4 Click Save.
Configuring MAC Address Filtering
MAC address filtering allows you to block traffic coming from certain known
machines or devices. The router uses the MAC address of a computer or device
on the network to identify it and block or permit the access. Traffic coming in from
a specified MAC address will be filtered depending upon the policy.
Cisco RV180/RV180W Administration Guide
93
Configuring the Firewall
Configuring Advanced Firewall Settings

To enable MAC address filtering:
STEP 1 Choose Firewall > Advanced Settings > MAC Filtering.
STEP 2 Check the Enable box to enable MAC Address Filtering for this device. Uncheck
the box to disable this feature.
If you enable MAC filtering, in the Policy for MAC Addresses Listed Below field,
choose one of the following options:
•
Block and Allow the Rest—Choose this option to block the traffic from the
specified MAC addresses and to allow traffic from all other addresses.
•
Allow and Block the Rest—Choose this option to allow the traffic from the
specified MAC addresses and to block traffic from all other machines on the
LAN side of the router.
For example, two computers are on the LAN with MAC addresses of
00:01:02:03:04:05 (host1), and 00:01:02:03:04:11 (host2). If the host1 MAC address
is added to the MAC filtering list and the “block and allow the rest” policy is
chosen, when this computer tries to connect to a website, the router will not allow
it to connect. However, host2 is able to connect because its MAC address is not in
the list. If the policy is “allow and block the rest,” then host1 is able to connect to a
website, but host2 is blocked because its URL is not in the list. The MAC filtering
policy does not override a firewall rule that directs incoming traffic to a host.
STEP 3 In the MAC Addresses table, click Add.
STEP 4 Enter the MAC address and description to add to the table and click Save. Repeat
for each address to allow or block.
STEP 5 Click Save.
Configuring IP/MAC Address Binding
IP/MAC Binding allows you to bind IP addresses to MAC address. Some machines
are configured with static addresses. To prevent users from changing static IP
addresses, IP/MAC Binding should be enabled. If the Cisco RV180/RV180W sees
packets with matching IP address but inconsistent MAC addresses, it drops those
packets.

When you create a firewall rule, you can specify a service that is controlled by the
rule. Common types of services are available for selection, and you can create
your own custom services. This page allows creation of custom services against
which firewall rules can be defined. Once defined, the new service will appear in
the List of Available Custom Services table.

Configuring Internet Group Management Protocol (IGMP)
Internet Group Management Protocol (IGMP) is an exchange protocol for routers.
Hosts that want to receive multicast messages need to inform their neighboring
routers of their status. In some networks, each node in a network becomes a
member of a multicast group and receives multicast packets. In these situations,
hosts exchange information with their local routers using IGMP. Routers use IGMP
periodically to check if the known group members are active. IGMP provides a
method called dynamic membership by which a host can join or leave a multicast
group at any time.

Configuring Virtual Private Networks (VPNs)
and Security
This chapter describes VPN configuration, beginning with the “Configuring
VPNs” section on page 104. It also describes how to configure router security,
beginning with the “Configuring Security” section on page 121.
The following sections are covered:
•
Configuring VPNs, page 104
•
Configuring a Basic VPN, page 107
•
Configuring Advanced VPN Parameters, page 109
•
Configuring Security, page 121
Configuring VPNs
A VPN provides a secure communication channel (“tunnel”) between two gateway
routers or a remote worker and a gateway router. You can create different types of
VPN tunnels, depending on the needs of your business. Several scenarios are
described below. Read these descriptions to understand the options and the
steps required to set up your VPN.

Site-to-Site Access with Gateway-to-Gateway VPN
A gateway-to-gateway VPN connects two or more routers using an IPsec policy to
secure traffic between two sites. Use this type of VPN if you need to connect the
network at a branch office to the network at your main office, for example.
1. Use the Basic VPN Setup page to create a VPN. Choose Gateway as the peer
type, and enter the following:
•
new connection name
•
pre-shared key
•
remote gateway type and remote WAN IP address or fully-qualified domain
name (FQDN)
•
local gateway type and local WAN IP address or FQDN
You will also need to configure the corresponding settings on the router at
the other site. See Configuring a Basic VPN, page 107.
2. If needed, edit the default settings by using the Advanced VPN Setup page.
See Configuring Advanced VPN Parameters, page 111.
Remote Access with an IPsec Client (Client-to-Gateway VPN)
In this scenario, a remote client, such as a PC running IPsec VPN client software,
initiates a VPN tunnel. The IP address of the remote PC client is not necessarily
known in advance. The gateway acts as responder. Configure this type of VPN
tunnel if you have a teleworkers who need to securely connect to your network
from their home offices, for example.
You will need to configure this router with the specific IPsec policies required for
the IPsec client. You also will need to install and configure the IPsec client
software on the users’ computers.
1. Use the Basic VPN Setup page to quickly configure the IKE Policy and the VPN
Policy by using the standard settings. Choose VPN Client as the peer type, and
enter the other basic settings. Note that the users’ VPN client software will need
to be configured with the same Pre-Shared Key that you enter here. See
Configuring a Basic VPN, page 107.
2. To configure the settings required by the VPN client software, use the
Advanced VPN Setup page to edit the IKE Policy and the VPN Policy. For the
required settings, refer to the VPN client documentation. See Configuring
Advanced VPN Parameters, page 109.

3. Set up the users:
•
If you configured the VPN policy to authenticate from the local database,
add the users on the VPN > IPsec > VPN Users page. Choose XAUTH as
the user protocol. (See Configuring VPN Users, page 119).
•
If you configured the VPN policy to authenticate from an external database,
configure the connection to the RADIUS server. See Using the Cisco
RV180/RV180W With a RADIUS Server, page 125.
Remote Access with Cisco QuickVPN
For quick setup with basic VPN security settings, distribute Cisco QuickVPN
software to your users, who can then securely access your network resources.
Use this option if you want to simplify the VPN setup process. You do not have to
configure VPN policies. Remote users can connect securely with the Cisco
QuickVPN client and an Internet connection.
1. Add the users on the VPN > IPsec > VPN Users page. Choose QVPN as the user
protocol. See Configuring VPN Users, page 119.
2. Instruct users to obtain the free Cisco QuickVPN software from Cisco.com, and
install it on their computers. For more information, see.Appendix A, “Using
Cisco QuickVPN for Windows 7, 2000, XP, or Vista.”
Note: To enable access via Cisco QuickVPN this router, you must enable remote
management to open port 443 for SSL. See Using the Management Interface,
page 134.
Remote access using PPTP
In this scenario, a remote user with a Microsoft computer connects to a PPTP
server at your site to access network resources. Use this option to simplify VPN
setup. You do not have to configure VPN policies. Remote users can connect by
using the PPTP client from a Microsoft computer. There is no need to install a VPN
client. However, be aware that security vulnerabilities have been found in this
protocol.
Enter the PPTP server settings and add the users on the VPN > IPsec > VPN
Users page. Choose PPTP as the user protocol. See Configuring VPN Users,
page 119.

VPN Policy table, click Add or select an existing policy and click Edit.
NOTE To create an Auto VPN Policy, you need to first create an IKE policy and then add the
corresponding Auto Policy for that IKE Policy.
STEP 1 At the top of this page, enter these settings:
•
Policy Name—Enter a unique name to identify the policy.
•
Policy Type—Choose one of the following options:
-
Auto Policy—Some parameters for the VPN tunnel are generated
automatically. This requires using the IKE (Internet Key Exchange)
protocol to perform negotiations between the two VPN Endpoints.
-
Manual Policy—All settings (including the keys) for the VPN tunnel are
manually input for each end point. No third-party server or organization is
involved.
•
Remote Endpoint—Select the type of identifier that you want to provide for
the gateway at the remote endpoint: IP Address or FQDN (Fully Qualified
Domain Name). Then enter the identifier in the space provided.
•
NETBIOS—Check the Enable box to allow NetBIOS broadcasts to travel
over the VPN tunnel, or uncheck this box to disable NetBIOS broadcasts over
the VPN tunnel. For client policies, the NetBIOS feature is available by
default.
STEP 2 In the Local Traffic Selection and Remote Traffic Section, enter these settings:
•
Local/Remote IP—Select the type of identifier that you want to provide for
the endpoint:
-
Any—Specifies that the policy is for traffic from the given end point (local
or remote). Note that selecting Any for both local and remote end points
is not valid.
-
Single—Limits the policy to one host. Enter the IP address of the host that
will be part of the VPN in Start IP Address field. Then enter the IP address
in the Start Address field.
-
Range—Allows computers within an IP address range to connect to the
VPN. Enter the Start IP Address and End IP Address in the provided fields.
Enter the first IP address of the range in the Start Address field. Enter the
final IP address of the range in the End Address field.

Subnet—Allows an entire subnet to connect to the VPN. Enter the
network address in the Start IP Address field, and enter the Subnet Mask
in the Subnet Mask field. Enter the subnet’s network IP address in the
Start Address field. Enter the subnet mask, such as 255.255.255.0, in the
Subnet Mask field. The field automatically displays a default subnet
address based on the IP address.
IMPORTANT: Make sure that you avoid using overlapping subnets for
remote or local traffic selectors. Using these subnets would require
adding static routes on the router and the hosts to be used.
For example, a combination to avoid would be:
Local Traffic Selector: 192.168.1.0/24
Remote Traffic Selector: 192.168.0.0/16
STEP 3 In the Split DNS section, check the Enable box to allow the Cisco RV180/RV180W
to find the DNS server of the remote router without going through the ISP (Internet).
Otherwise, uncheck the box to disable this feature. If you enable Split DNS, also
enter these settings:
•

After the specified number of kilobytes of data is transferred, the SA is
renegotiated. The minimum value is 1920000 KB.
-
When configuring a lifetime in kilobytes (also known as lifebytes), be
aware that two SAs are created for each policy. One SA applies to
inbound traffic, and one SA applies to outbound traffic. Due to differences
Cisco RV180/RV180W Administration Guide
116
Configuring Virtual Private Networks (VPNs) and Security
Configuring Advanced VPN Parameters
5
in the upstream and downstream traffic flows, the SA may expire
asymmetrically. For example, if the downstream traffic is very high, the
lifebyte for a download stream may expire frequently. The lifebyte of the
upload stream may not expire as frequently. It is recommended that the
values be reasonably set, to reduce the difference in expiry frequencies
of the SAs; otherwise the system may eventually run out of resources as
a result of this asymmetry. The lifebyte specifications are generally
recommended for advanced users only.
•
Encryption Algorithm—Select the algorithm used to encrypt the data.
•
Integrity Algorithm—Select the algorithm used to verify the integrity of the
data.
•
PFS Key Group—Check the Enable box to enable Perfect Forward Secrecy
(PFS) to improve security. While slower, this protocol helps to prevent
eavesdroppers by ensuring that a Diffie-Hellman exchange is performed for
every phase-2 negotiation.
•
Select IKE Policy—Choose the IKE policy that will define the
characteristics of phase 1 of the negotiation. To add an IKE policy to the list,
click the IKE Policies link. See Configuring Advanced VPN Parameters,

NOTE You can also created comma-separated value (CSV) files containing user
information and import them to easily add multiple users. See Importing CSV Files,
page 149.
VPN clients must be configured with the same VPN policy parameters used in the
VPN tunnel that the client wishes to use: encryption, authentication, lifetime, and
PFS key-group. Upon establishing these authentication parameters, the VPN client
user database must also be populated with an account to give a user access to
the tunnel. The VPN gateway authenticates users in this list when XAUTH is used
in an IKE policy.
VPN client software is required to establish a VPN tunnel between the router and
remote endpoint. Open source software (such as OpenVPN or Openswan) as well
as Microsoft IPsec VPN software can be configured with the required IKE policy
parameters to establish an IPsec VPN tunnel. Refer to the client software guide for
detailed instructions on setup as well as the router’s online help.

Configuring Security
The Cisco RV180/RV180W provides several security methods, including
certificate authentication, RADIUS server support, and 802.1x port-based
authentication.
Using SSL Certificates for Authentication
The Cisco RV180/RV180W uses digital certificates for IPsec VPN authentication
and SSL validation (for HTTPS and SSL VPN authentication). You can obtain a
digital certificate from a well-known Certificate Authority (CA) such as VeriSign, or
generate and sign your own certificate using functionality available on this
gateway. The gateway comes with a self-signed certificate, and this can be
replaced by one signed by a CA as per your networking requirements. A CA
certificate provides strong assurance of the server's identity and is a requirement
for most corporate network VPN solutions.
Cisco RV180/RV180W Administration Guide
121
Configuring Virtual Private Networks (VPNs) and Security
Configuring Security
5
A self certificate is a certificate issued by a CA identifying your device (or selfsigned if you don't want the identity protection of a CA). To request a self
certificate to be signed by a CA, you can generate a Certificate Signing Request
from the gateway by entering identification parameters and sending to the CA for
signing. Once signed, the CA's Trusted Certificate and signed certificate from the
CA are uploaded to activate the self-certificate validating the identity of this
gateway. The self certificate is then used in IPsec and SSL connections with peers
to validate the gateway's authenticity.
To configure certificates, choose Security > SSL Certificate. You can choose the
following options:
•
Trusted Certificates—Upload a certificate from a trusted authority (for
example, a certificate Authority such as Microsoft or VeriSign). See
Uploading a Trusted Certificate.
•
Self Certificates—Upload a certificate that has been generated from the
Cisco RV180/RV180W, and either signed by a CA, or self-signed. See
Uploading a Self Certificate.
•
Self Certificate Requests—Generate a self-certificate request to give to a
CA for signing, or to self-certify. See Generating New Certificate
Requests.
•
Export Router Certificate—Export a router certificate to give to clients who
want to connect to the router and use the certificate for authentication. See
Exporting the Router’s Current Certificate.
Uploading a Trusted Certificate
If you have a certificate from a trusted authority to upload, the file must be located
on the computer connected to the Cisco RV180/RV180W. Perform the following
steps:
STEP 1 Choose Security > SSL Certificate.
STEP 2 In the Trusted Certificates (CA Certificate) Table, click Upload.
STEP 3 Click Browse and locate the file on your computer.
STEP 4 Click Upload. The new certificate appears in the table.

Generating New Certificate Requests
One of the steps in creating a certificate is to generate a certificate request from
the computer or the device that will be using the certificate. The Certificate
Signing Request (CSR) file needs to be submitted to the CA who will then
generate a certificate for this device.
To generate a certificate request:
STEP 1 Choose Security > SSL Certificate.
STEP 2 Under Self Certificate Requests, click Generate Certificate.
STEP 3 Enter the name of the certificate request.
STEP 4 Enter the subject of the certificate request. The Subject field populates the CN
(Common Name) entry of the generated certificate. Subject names are usually
defined in the following format:
CN=, OU=, O=, L=, ST=, C=.
For example, CN=router1, OU=my_company, O=mydept, L=SFO, C=US.
STEP 5 Choose the Hash Algorithm: MD5 or SHA-1. The algorithm used to sign the
certificate (RSA) is shown.
STEP 6 Enter the signature key length, or the length of the signature (512,1024, or 2048).
STEP 7 (Optional) Enter the IP address of the router.
STEP 8 (Optional) Enter the domain name of the router.
STEP 9 (Optional) Enter the e-mail address of the company contact that is used when

Importing CSV Files
To save a copy of your router’s mirror configuration, click Backup Mirror
Configuration. The browser downloads the configuration file and prompts you to
save the file on the PC.
The mirror image is the last working configuration. The startup configuration is the
configuration that the device used to boot up. The startup and mirror
configurations can differ. For example, if you made changes to the current
configuration but forgot to save it, after 24 hours, the device automatically saves
the currently-running configuration as the “mirror” image. But if the device crashed
during the 24 hour window, then the device will use the startup configuration to
boot up.
To copy the mirror configuration file to the startup configuration file, click Copy
Mirror to Startup. This replaces the startup configuration file with the mirror
configuration file. You may want to do this if the device crashed and you had to
reset the device to factory defaults. After you perform the factory reset, the mirror
image is not erased, and you can copy it to the startup configuration to allow the
device to use the configuration to boot up.
Importing CSV Files
You can import VPN client setting files that contain the username and passwords
of clients in a Comma Separated Value (CSV) text file. You can use Excel to create
a CSV file containing the VPN client settings. The file should contain one row for
the headings and one or more rows for the VPN clients. For example, the following
specifies the settings of two users (a PPTP user and a QuickVPN user) to import:
